What changes the price

Three main factors.

1. Square footage

The average pro rate sits around $0.40 to $0.80 per square foot in Montreal. A 350 sq ft driveway runs $140 to $280. The bigger the surface, the lower the per-sq-ft rate.

2. Access

Ground-level, no obstacles: standard rate.
Upper floor, balcony, roof: add 25–50%.
Limited access (no water nearby, electricity far): add 10–20%.

3. Dirt level

Normal dirt (dust, pollen): standard rate.
Mildew or algae: add 15% (detergent needed).
Oil, paint, graffiti stains: custom pricing, often +$50 to $150.

DIY or hire pros?

Fair question. Honest answer below.

When to DIY

You already own a quality pressure washer (1,800 PSI minimum, fan-tip nozzle).
The surface is simple (flat driveway, no delicate pavers).
You've got 3-4 hours to commit (including setup and cleanup).
You know how to mix detergent so you don't stain the house siding.

Cost of an entry-level pressure washer: $250-400 (buy). Rental: $80-120 for 24h at Home Depot or Location Légaré.

When to hire pros

You have paver driveways with polymeric sand (risk of blasting it all out).
You want to wash the house siding (risk of pushing water behind it).
You have a roof to clean (always soft-wash, never high pressure).
You have an aging wood deck (risk of ripping fibers).
You have more than 2 hours of surface (time savings justify the cost).

Common mistakes that cost more later

Buying a washer under 1,600 PSI. You scrub for hours with no result.
Maxing out pressure on everything. You blast out polymeric sand, split wood, crack vinyl.
Skipping detergent. Water alone removes dust. Not mildew. The right product does 70% of the work.
Washing bottom-to-top on a house. You leave streaks. Always wet top-down, soap, then rinse bottom-up.
Ignoring weather. Too hot and soap dries before rinsing. Too cold and detergent doesn't react.

Bundles cut the cost

If you do three items in the same visit, most companies (us included) offer 15-25% off the total. Example:

Paver driveway alone: $225
Deck alone: $275
Pool surround alone: $175
À la carte total: $675
Bundle (–20%): $540

How much does washing a paver driveway cost in Laval? +

$125 to $400 depending on size (350-600 sq ft), access, and dirt level. The typical average is $200 to $275.

Can pressure washing damage my pavers? +

Yes if done wrong. A pro tunes pressure and angle to avoid blasting out polymeric sand. If sand is displaced, we top it up after.

Should I wash my roof? +

If you see black streaks (algae) or moss, yes. But only soft-wash (low pressure + solution). Never high pressure on shingles.

When's the best season? +

April to June for spring cleanup. September to October for pre-winter cleaning. Avoid days over 30 °C.

Do you offer bundles? +

Yes. Driveway + deck + pool surround typically gets 15-25% off the à la carte price.
